Adding 4.5-leaf springs to your early model Mustang will provide a firmer ride than 4-leaf springs, but not as harsh as 5-leaf springs. In addition to an improved ride, this setup helps prevent wheel hop and axle wrap during hard acceleration.

For those looking to lower their car's center or gravity, the mid-eye mounting lowers the rear of the car about one inch. Finished with a steel-gray paint to more closely resemble OEM appearance, this kit includes everything needed for installing driver and passenger side rear leaf springs.

Hello. Can I ask one question please. What is the reference of the shackles included in the kit : C6ZZ-5776-GT or C5ZZ-5776-GTL . Beacause, I have a Mustang Fastback 1968 with dual exhaust flowmaster. Thanks in advance for your advice. Regards. Ronan
